Abstract

The utility model discloses an auxiliary hook for cataract ultra-emusification operations, which is composed of a hook handle and a hook needle, and a cutting edge is arranged on the bent part of the inside of the hook needle. The utility model has the advantages of reasonable and ingenious design and high safety. Besides the general functions of other ophthalmic operation auxiliary hook, the utility model can cut mature nuclei and brown hard nuclei into blocks which are easy to emulsify with an ultra-emusification head, and the impossibility of the ultra-emusification of hard nucleus cataract is changed into possibility. The utility model also has a plurality of functions. The auxiliary hook for cataract ultra-emusification operations can replace iris hooks for separating irises and pulling away the irises, and replaces polishers for polishing rear bursa, etc. The design has the advantages of simple structure, low cost, convenient use and safe operation. The irises, the cyst membranes and the cornea can not be scratched and hurt.

Description

The ultrasonic emulsification for cataract auxiliary hook

This utility model relates to the ophthalmologic operation assistive device, particularly the ultrasonic emulsification for cataract auxiliary hook.

Ultrasonic emulsification for cataract is since invention, and doctors think that phacoemulsification only is fit to soft nuclear cataract, and is unaccommodated to ripe stone and sepia nuclear cataract, like this, makes ultrasonic emulsification for cataract be subjected to fixed limitation in therapeutic domain.

The purpose of this utility model is: a kind of safe, easy to operate ultrasonic emulsification for cataract auxiliary hook reasonable in design, exquisite is provided, uses this utility model, can make phacoemulsification successfully be applicable to ripe cataract extraction in sclerotic nucleus cataract and sepia nuclear cataract.

This utility model is achieved in that by the neck of hook (1), crochet hook (2) to be formed, and the neck of hook (1) lower end connects crochet hook (2), and the inboard turn of bilge of crochet hook (2) has a blade (3).

This utility model compared with prior art has following advantage:

1, safety reasonable in design, exquisite, except that possessing other ophthalmologic operation auxiliary hook general utility functions, because of the inboard turn of bilge at crochet hook has designed a blade, maturation nuclear and brown stone can be cut into block emulsifying easily with first of ultrasonic emulsification, thereby quickened the ultrasonic emulsification process, made the ultrasonic emulsification cataract extraction in sclerotic nucleus cataract from not becoming possibility.

2, the utlity model has multiple function, can substitute iris hook and make iris and separate and draw back iris, substitute polisher and do back capsule polishing, separate on the capsule of back machine film etc., the smooth circle of top periphery of hook is blunt, can not hang wound to iris, cyst membrane, cornea.

3, this utility model novelty simple in structure, cost is low, and is easy to use, handling safety.

This utility model should adopt rustless steel, the material of flexible.

Accompanying drawing 1 is this utility model structural representation;

Accompanying drawing 2 is accompanying drawing 1 crochet hook partial structurtes sketch maps;

Embodiment of the present utility model:

Rustless steel with flexible is a material, and auxiliary hook shank (1) is 3 * 5 * 100mm ², the neck of hook (1) lower end connects crochet hook (2) and is the long 15mm of 0.5-0.5, and the inboard turn of bilge of crochet hook (2) has designed the blade (3) that has 0.3mm long, and the outward appearance circle of hook is blunt smooth, and the auxiliary hook of design can free in and out the auxiliary mouth of cornea of 1mm.

Claims

1, a kind of ultrasonic emulsification for cataract auxiliary hook is made up of the neck of hook (1), crochet hook (2), it is characterized in that: the neck of hook (1) lower end connects crochet hook (2), and the inboard turn of bilge of crochet hook (2) has a blade (3).
